A Rambling Walk Through an EMV Transaction

With Visa and Mastercard pushing for EMV (http://www.emvco.com, aka “chip and pin”) rollout in the United States, the uptake of contactless payment and the use of mobile NFC wallets, the chipcard security community will soon be getting more eyes to analyze the protocols in use with chip and contactless credit card transactions.

This talk won’t present any innovative attacks on the EMV system. Instead, we’ll perform a single EMV transaction on stage, exploring every command. Along the way we’ll discuss the plethora of standards and technologies surrounding EMV, elaborate the data structures used and try to put into perspective some of the better known attacks on the system. Afterwards you should have enough information to plug in your own card and start hacking.
